There is no way that Ellen Marshal is daughter of William Marshal, 2nd Earl of Pembroke, Magna Carta Surety = William Marshal, 2nd Earl of Pembroke, Magna Carta Surety MP
If i read the about me correctly for William Marshal, 2nd Earl of Pembroke, Magna Carta Surety it states the following "Posterity William had no heirs, and his titles passed to his younger brother, Richard "
Thus the lineage provide here is WRONG - and also these profiles also already exist on GENI as MP's
William Marshal, 2nd Earl of Pembroke, Magna Carta Surety = William Marshal, 2nd Earl of Pembroke, Magna Carta Surety MP
William Marshal, Sir, 1st Earl Pembroke = William Marshal, 1st Earl of Pembroke MP
If Ellen Marshal 's father was indeed a William Marshall we was definitely not the son of William Marshal, Sir, 1st Earl Pembroke = William Marshal, 1st Earl of Pembroke MP more research is needed to find her correct father and place him into the Marshall ancestry.
Ellen Marshal
Gender: Female
Wife of Robert De Mautby
These been tacked on by another as her parents/grandparents William Marshal, 2nd Earl of Pembroke, Magna Carta Surety = William Marshal, 2nd Earl of Pembroke, Magna Carta Surety MP

I'd take a second look at the FabPedigree line - for once they may be onto something (if not just *on* something*). William THE Marshal's older brother John was a rather bad boy, but his escapade with his mistress was the main reason the Marshall name didn't just die out in the 13th-14th century like so many others.
*That* Marshall line has been much less studied, because most people are, of course, more interested in William....
Nice little chart and some gossip here: http://sinclairgenealogy.info/marshal-family
...the Marshal estates – so carefully accumulated during Earl William’s career – were broken up and parcelled out among the heirs of his daughters. In 1246, the title of Marshal of England passed to Roger Bigod, the son of William Marshal’s eldest daughter Matilda. Through lack of luck, long life and fertility, the male line of the Marshal dynasty was brought to a desperately premature end.
Asbridge, Thomas. The Greatest Knight (p. 378). Ecco. Kindle Edition.
It seems to appear, any if us who can claim descendancy would have to be from the daughters of William I.
William Marshal’s heirs were neither indolent, nor foolish, but they did lack their father’s inimitable ability to navigate the fractious world of medieval politics. Most crucially of all, they proved unable to sire heirs.....As a result, the Marshal estates – so carefully accumulated during Earl William’s career – were broken up and parcelled out among the heirs of his daughters.
(from Asbridge, Thomas. The Greatest Knight.)
There are some possible collateral connections - an uncle also named William and nicknamed "Giffard" (Chubby-cheeks), older rascal brother John and his descendants, and a presumed younger brother Anselm, who may or may not have left descendants.
While it's not as good as a direct line of descent, at least it's *something*.
